Bosch HC8531
Previous reviewer's information on this bit is incorrect. This bit is a designed to be used in a rotary hammer, not a chisel. It works very well at this job - won't cut through rebar (the carbide teeth catch in it, and you may damage the bit if you really try to push through it), but through any kind of masonry (I've used it on concrete, block, and brick) it moves very quickly and leaves extremely clean holes. No blowout in brick at all, great for making clean vent holes, etc.0 of 1 people found the following review helpful.
